“…The Ba-modified Pb(Zr 1-x Ti x )O 3 (PBZT) ceramic composition remains for many years an interesting ferroelectric material, as a result of interesting physical properties (very high value of electrical permittivity weakly depending on temperature) [6][7][8][9][10]. The PBZT ceramic materials with ferroelectric relaxor properties have been reported as a good candidate for microelectronic applications [11][12][13]. Examples of such applications can be electrostrictive actuators due to large electrostrictive strain, transducers, sensors, etc.…”

In the work, the multicomponent Pb 0.75 Ba 0.25 (Zr 0.65 Ti 0.35 ) 1-a Sn a O 3 (PBZT/Sn) ceramics were obtained with various tin amounts (a from the range of 0.0 to 0.1). The densification of the PBZT/Sn ceramic samples was performed using pressureless sintering method. The effect of SnO 2 content on the crystal structure of PBZT/Sn ceramics, microstructure, DC electrical conductivity and electrophysical properties (including dielectric and ferroelectric testes), were investigated. The PBZT/Sn ceramic samples exhibit high values of dielectric permittivity at the temperature of ferro-paraelectric phase transition and show the relaxor character of phase transition. Excessive SnO 2 contents doping of the PBZT/Sn materials (already for a = 0.1) might lead to lattice stress and structure defects, which successively leads to the deterioration of ferroelectric and dielectric properties of the ceramic samples. The presented research shows that the addition of SnO 2 to the base PBZT compound (in the proper proportion) gives an additional possibility of influencing the parameters essential for practical applications, from the areas of micromechatronics and microelectronics.

“…The largest groups of materials with these properties are materials with a perovskite structure. Generally, perovskite ceramics (the best materials for smart structures, sensors and actuators) are fabricated by solid-state reactions or wet-chemistry methods [7][8][9][10]. The methods are related to high production costs and have serious disadvantages (e.g., hightemperature treatment during the technological process results in coarsening and aggregation of the particles or non-stoichiometric composition or nonperovskite structure of the final materials due to the appearance of the volatile element out-diffusion at high temperature).…”

Physical properties of lead-free BaFe1/2Nb1/2O3 ceramics obtained from mechanochemically synthesized powders

Modern electronics expect functional materials that are eco-friendly and are obtained with lower energy consumption technological processes. The multiferroic lead-free BaFe 1/2 Nb 1/2 O 3 (BFN) ceramic powder has been prepared by mechanochemical synthesis from simple oxides at room temperature. The development of the synthesis has been monitored by XRD and SEM investigations, after different milling periods. The obtained powders contain large agglomerates built by crystals with an estimated size about 12-20 nm depending on the period of milling. From this powder, the multiferroic BFN ceramic samples have been prepared by uniaxial pressing and subsequent sintering pressureless method. The morphology of the BFN ceramic samples strongly depends on high-energy milling duration. The properties of the ceramic samples have been investigated by dielectric spectroscopy, in broad temperature and frequency ranges. The high-energy milling of the powders has strongly affected the dielectric permittivity and dielectric loss of the BaFe 1/2 Nb 1/2 O 3 ceramic samples. The usage of the mechanochemical synthesis to obtain the multiferroic lead-free BFN materials reduces the required thermal treatment and simultaneously improves the parameters of the BFN ceramics.

“…An appropriate selection of the composition (from rhombohedral, tetragonal phases or morphotropy area), opportunely doping the basic composition and conditions of a technology ceramic powders and samples allows obtaining the materials, which can be used widely in different types of piezoelectric transducers, electronic sensors, actuators, resonators and filters for microelectronics and micromechatronics [8][9][10]. For PZT-type ceramics from morphotropic region (first of all Zr/Ti = 0.52/0.48) the physical parameters of ceramics are usually extremely high or extremely low what is very important for applications [11]. To improve piezoelectric and other properties, the base composition PZT is admixed [12,13].…”

Abstract. In this paper the multicomponent PZT-type solid solution doped by barium, calcium, strontium, bismuth and germanium with composition: Pb0.975Ba0.01Ca0.01Sr0.005(Zr0.52Ti0.48)O3 + 1.4 wt.% Bi2O3 + 0.3 wt.% GeO obtained by hot uniaxial pressing method is described. The results of structural, dielectric, ferroelectric and electromechanical studies of these ceramics are presented. It has been stated that introduction to the basic composition PZT admixtures of the barium, calcium, strontium, bismuth and germanium has a positive effect on the electro-physic parameters of obtained ceramic samples. This material has good microstructure, with high value of the dielectric permittivity (with the high temperature of phase transition) as well as low dielectric losses. It allows considering this material as elements for low frequency and high temperature electromechanical transducers.
